Title: Hydrogel of high refractivity produced as polymer and copolymer of n-benzyl-n-methylacryl amide
Inventor: LIZAU SHUGAO
IPC: A61L27/00
Filed: 1997-03-17
Abstract: PURPOSE: Hydrogel which can be used for lens in eyeball should have proper size, high moisture content and high refractivity, and be optically transparent and stable for long time. The properties are largely dependent on hydrogel structure. Selection of proper co-monomer and cross-linking agent is important because most hydrogel consists of cross-linked copolymer. CONSTITUTION: N-Benzyl-N-methylacrylic amide(BMA) copolymer, new serial compound, is optically transparent and stable for long time and has high moisture content, high refractivity and high strength. The co-monomer may be derivatives of acrylic acid such as acrylate, methacrylate, acrylic amide, vinyl-substituted amide or nitrogen-containing heterocyclic compound. Optically transparent biocompatibility hydrogel is formed by cross-linking and hydrating of the copolymer. The produced hydrogel is useful for lens eyeball and related uses and is stronger than conventional hydrogel.

Abstract: PURPOSE: A method for managing a signal link state according to a call switching of a wireless local loop(WLL) data service is provided to decrease loads of a system according to a collection of state information of the signal link between an IWF(Inter Working Function) and a BSC(Base Station Controller) and prevent a mismatch phenomenon between state information referred in a state management block and a call process block for improving a data accuracy by collecting state information of the signal link between the IWF and the BSC from the state management block and approaching the call process block to a shared memory to grasp a state of the signal link. CONSTITUTION: If a state transition of a FR/PRI(Frame Relay/Primary Rate Interface) signal link is generated, an IIU(IWF Interface Unit) state management block informs a state of the FRI/PRI signal link to a CCP(Call Control Processor) state management block(S11,S12). The CCP state management block records the state of the transitted FR/PRI signal link in a shared memory, and processes an IIU resource corresponding to the signal link as a using impossibility to record the processed IIU resource in the shared memory when the state of the FR signal link or the state of the PRI signal link is not an active state(S14,S15). If the FR/PRI signal link is the active state, CCP state management block processes the IIU resource corresponding to the signal link as a using possibile state to record the processed IIU resource in the shared memory(S14,S16). If a call for requesting a WLL data service is received from a BSC, a CCP call control block is approached to the shared memory for checking a state of the IIU resource(ST17,ST18). If the state of all IIU resources is a using impossible state as a result of the check, the CCP call control block rejects the call(ST19,ST21). If the state of all IIU resources is not a using impossible state as a result of the check, the CCP call control block permits the call to activate the FR signal link and the PRI signal link to an IIU call control block(ST20).

Abstract: PURPOSE: A switching channel management method in communication process system is provided to monitor the status of each switch channel so as to recover and report when a failure occurs. CONSTITUTION: A switching sensor unit(31) in the switching board(30) senses whether receive data has been received in a channel board periodically. If the switching sensor unit(31) senses receive data, the switching sensor unit(31) reports to a main switching unit(32) in the switching board(30) and requests switching. The main switching unit(32) verifies whether switching can be performed to the other channel board where the received data will be transmitted, and sends out the information of the channel to a channel status monitoring circuit unit(33). The channel status monitoring circuit unit(33) stores the information of the channel until a new information of the channel for next switching is received. If nothing is wrong with the status of the channel, the switching board(30) requests a transmission/receive buffer control execution to the data sensor unit and the buffer control unit of the channel board. The switching board also requests transmission buffer control execution to the data sensor unit and the buffer control unit of the other channel board where the received data will be transmitted. The received data saved in the receive buffer is transmitted to a transmission buffer of a transmission part, and the received data is sent out to a destination node. If the verified channel status is abnormal, the channel board where the received data will be transmitted becomes reset and recovers to a normal status.
